I was able to test the 2021 N660E against the more expensive N620E and here's what I think of them: The N660E is a great 1080 camera with a dual mic. Connecting to my Lenovo IdeaPad Flex is easy as it was recognized straight away so no drivers or software to download. The light ring works well with 3 intensity levels. However: 1) The displays do not turn on automatically when you start Zoom VC. as in the N620E model. You have to turn the light on manually and turn it off the same way. 2) They only have the white light option (5000K not tested). Yellow light (3000K) cannot be used, which is possible on the N620E3. The camera hinge design is limited on the N660E. The camera has a semicircular frame attached to the base. To tilt the camera up, the camera is limited by the cable on the back and cannot be tilted up more than 20-30 degrees. Not that big a downside, but the design of the N620E is much better. 4) N660E only has 30 fps while N620E has 60 fps. For general users like me, trying to talk to customers isn't a problem, but if you have a lot of people in a conference room, a higher frame rate per second is better for your VCH. Despite all that, the quality of this N660E camera is really good, durable and qualitative. All you have to do is evaluate whether the $20 price difference is worth the listed differences.
